AXLE-SKEIN.

SPECIFICATION forming part of Letters Patent No. 544,325, dated August13, 1895.

Application filed April25,1895. Serial Nb. 547,109. (No model.)

To all whom it may concern:

Be it known that I, JOHN SALAY, a citizen of the United States, residingat South Bend, in the county of St. Joseph and State of Indiana, haveinvented certain new and useful Improvements in Axle-Skeins, of whichthe following is a specification,

Heretofore malleable iron or steel axleskeins have been made of a singlepiece of sheet metal struck up and joined at its side edges in a singlelongitudinal Weld and comprising a skein portion proper, a collarportion, and a socket back portion, all made integral and fitted with ascrew-threaded plug of suitable material and proper size to fill thetubular outer end of the skein portion in which it is placed, and towhich itis secured by shrinking or welding. AXIe-skeins so formed havebeen imperfect at the junction .of the collar or shoulder with thejournal and socket portions, Where the greatest strength is required,and in some instances this weakness has been reinforced by a separatecollar shrunk or applied thereon in various ways, and this expedient hasalso been found expensive and defective.

The object of my invention is to provide an' axle-skein which willcomprise a socket-collar and journal portion, both securely weldedtogether, the collar portion being reinforced by additional folds orthicknesses of material, which will thus secure at the desired point thegreatest degree of strength.

My invention consists, primarily and genorally, in a wagon-axle skeinmade of two plates, weldedtogether at the shoulder or 001-. lar section,and welded at their edges longitudinally, as will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view of theaxle-skein when finished. Fig. 2 is a plan or diagram of a blank to formthe socket portion; Fig. 3, a similar view of a blank to form thejournal portion; Fig. 4, a longitudinal section through the plates withthe lap-joints cri-mped and joined together, ready to be swaged orforged to the required shape; Fig. 5, a plan, and Fig. 6 a cross-sectionin line 03 a: thereof, showing the blanks after having received thefirst impression, Fig. 5 representing by dotted lines the overlappingedges of the said blanks after having received the second impression;

Fig. 7, a longitudinal section of an aXle-skein when completed inaccordance with my in- Vention.

Theblanks 1 and 2 are made of sheet metal, preferably steel, the blank 1to form the socket portion 3 and the blank 2 to form the journal portion4 of the axle-skein. A crimp 5, formed upon the inner edge of the blank1, and a crimp 6, formed upon the adjacent inner edge of the blank 2,serve to unite the plates when stamped up and forged together, and alsoform a collar 7 between the plates, composed of double overlying plaitswelded together, to provide a substantially solid collar of greaterthickness of material Where most required than at the other portions ofthe skein. I

The blank 1 has rearwardlyexpanding straight sides 8 extending to theline 9 of greatest Width, to provide, when finished, a solidoutwardly-tapering socket portion 10 to re ceive and completely span theend of the wooden axle, and at the line 9 the blank 1 is reduced firstupon straight lines 11 and then upon curved lines 12, to form a filletconnection with remaining straight lines 13, which extend convergentlyto the inner end of the said blankl, which is cut in a straight line atright angles to the longitudinal axis of the skei'n-blank. Arearwardly-extending trough or half-sleeve 10 is thus formed upon thesocket 10, which is held beneath the axle, and can be securely attachedthereto. The forward ends and angles'of the blank 1 are each notched andchamfered, respectively, at 14, to overlap each other with aninterlocking joint, (shown in dotted lines in Fig. 5,) to more securelyand accurately hold the said blanks at the point where they receive thefinal pressure or force of the blow when they are welded together. Theblank 2 also has notches 15 at the ends of the crimp 6 for a likepurpose, and thesides of said blank converge in straight lines to theforward end thereof, as shown in.

Fig. 3, both of the ends of the said blank being curved somewhatoutwardly, to provide square ends both at the lap-joint and at the outerend of the journal, as will be well un-' derstood by pattern-cutters.

The blanksl and 2, after being crimped in any well-known or preferredmanner, are placed together to overlap each other at their adjacentinner edges, as shown in Fig. 4, and beingheld upon suitable dies arefirststamped or struck up, as shown in Figs. 5 and 6, to a U shape incross-section and then struck up a second time by the aid of (lies and amandrel in a well-known manner, to complete the forging and welding ofthe plates into the finished form shown in Figs. 1 and 7, the skeinbeing supplied at its forward end with a plug 16 of suitable materialand proper size to fit the inner portion of the outer end of the skeinwithin which it is placed by passing through the tubular skein from itsinner and enlarged end, and is preferably fixed in position within theskein by welding the parts. The two blanks will thus be solidlyboundtogether to form a double lap-weld at their adjaceut edges and are eachwelded longitudinally with a lap-weld in conjunction therewith, thusproviding a hollow steel skein with a solid collar from two plates ofsheet metal securely welded together, which is in finish and in everyparticularsubstantially identical with the axle-skeins in general useand which may furthermore be so hardened and tempered as to form inevery respect a superior article, being lighter, less expensive tomanufacture, stronger, more durable, and possessing a smoother, harder,and better journalsurface than with cast skeins, and possessing muchgreater strength at the vital point or collar connection between thespindle and the socket than heretofore obtained with single sheets ofmetal forming the entire skein integral.

' I claim as my invention and desire to secure by Letters Patent 1. Anaxle skein comprising a s0cket,journal and collar formed of two sheetmetal blanks, each welded at their longitudinal edges and lap weldedtogether at the collar, substantially as described.

2. An axle skein comprising a socket section having a crimped inneredge, and ajournal section also having a crimped inner edge adapted tobe welded together to form an intermediate collar, substantially asdescribed.

3. An axle skein comprising two sheet metal blanks, one to form thesocket and the other to form the journal portion thereof struck up andwelded together, substantially as de scribed.

4. An axle skein of malleable sheet metal comprising two sections, eachhaving flanges,

one to overlay the other and welded together y to form an intermediatecollar, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

JOHN SALAY.
